One of the most intriguing, and fastest ways to make fold-forms are in the Rolled fold part of the system. Rolled folds use the special, even pressure of the rolling mill to work the metal. They are either a package folded up and put through the mill like a Heistad Cup or are set up so that one side of the fold has more layers than the other when it is put through the mill. These travel further than the side with less layers when rolled, and, restrained by them, the whole fold curves as a result. This page describes the steps to making a Plunkett fold. The Good fold is derived from a Plunkett fold. These kinds of folds work well when forged as well as in the mill....

The boat fold branch of T-folds is an interesting avenue. It permits you to have a curving, concave table, and to produce shaped tables as well as other complex derivations. The basic boat is begun by making a wedge T-fold. After the first angle is made the loop is tipped inthe other direction and pinched again to produce the boat pillow form.... (2005)Complete Story

Silicon carbide separating discs are superb for scoring metal for bending, particularly when the metal sheet is less than 4 or 5 cm across. While I was originally taught to use discs for catch building which involves only straight lines I discovered that they are superb for curved line scoring. Advantages include no disturbance of a textured sheet metal front surface while gaining enormous changes in plane. This is how many of my own pieces are done....
